Replacing Poulan Weed Eater Fuel Lines: A Step-By-Step Guide

If the fuel line on your Poulan weed eater has rotted away, you can replace it yourself. The fuel line goes from the carburettor, through a hole in the bottom of the fuel tank, and into the fuel filter assembly. The seal around the fuel line where it goes into the tank is created by the fuel line swelling. If your fuel line is too small, you may need to use some fuel-resistant sealant on the outside. There are also kits available that include the correct-sized hoses, a filter, and a primer bulb. When replacing the fuel line, it is recommended to also replace the carburettor and clean the carb.

The fuel line size

Another fuel line kit that fits Poulan Weed Eaters is the Husqvarna/Poulan/Weed Eater Gas Petrol Fuel Line Kit 530069599. This kit comes with two different sizes of fuel lines: 3/16" OD by 3/32" ID and 9/64" OD by 5/64" ID. This kit is suitable for fuel systems that use a primer bulb and fits several series of Husqvarna, Poulan, Weed Eater, Sears, and Craftsman units.

The fuel filter

To replace the fuel filter of your Poulan weed eater, you will need to purchase a replacement fuel filter. You can find these at hardware stores or online.

Once you have your replacement fuel filter, locate the fuel lines on your Poulan weed eater. The fuel filter will be situated somewhere along these lines. It is a small, cylindrical component that connects to the fuel lines.

Using a pair of pliers or a similar tool, carefully detach the fuel lines from either side of the fuel filter. Take note of how the fuel lines are attached, as you will need to replicate this when installing the new fuel filter.

With the old fuel filter removed, take the new fuel filter and attach it to the fuel lines, ensuring a secure connection. You may need to cut the fuel lines to fit the new filter, depending on the model of your Poulan weed eater and the replacement part. Ensure that you have a snug fit to prevent any fuel leaks.

After installing the new fuel filter, check for any signs of leakage and ensure that the fuel lines are securely connected. If you are satisfied that the new fuel filter is correctly installed, you can then refill the fuel tank and start the engine to test the weed eater.

The fuel line routing

First, it is important to understand the components involved in the fuel line system. The fuel line itself is a flexible hose that connects the fuel tank to the carburettor, allowing fuel to flow smoothly from the tank to the engine. The fuel filter is also an essential component, as it ensures that any contaminants or debris in the fuel are removed before it reaches the carburettor, preventing clogging or damage to the engine.

To begin the replacement process, remove the fuel tank from the weed eater. This will give you access to the fuel lines and the fuel filter. It is important to note that the routing of the fuel line may vary slightly depending on the model of your Poulan weed eater, but the basic principles remain the same.

Once the tank is removed, you will need to disconnect the old fuel lines from the carburettor and the tank. Take note of the routing of the lines, as you will need to replicate this when installing the new lines. Carefully pull the lines out of the tank, being mindful of any sharp edges that could damage the new lines.

Now, you are ready to install the new fuel lines. Cut the new lines to the appropriate length, ensuring that they are long enough to reach from the tank to the carburettor with a little slack for movement. It is recommended to cut the ends of the new lines at a 45-degree angle, as this will make it easier to push them into the tank and the carburettor.

Use a small, angled tool, such as needle-nose pliers, to guide the new lines into the tank. Gently push and manoeuvre the lines through the holes, being careful not to kink or damage the lines. Once the lines are in place, attach the fuel filter to the appropriate line, following the manufacturer's instructions.

Finally, reattach the fuel tank to the weed eater, ensuring that the lines are securely connected to the carburettor and that there is no slack or tension on the lines. Check that the lines are securely seated in the tank and that there are no leaks. Start the engine and check for any signs of fuel leakage. If there are no leaks, your new fuel lines are successfully routed and installed.

The fuel tank

To replace the fuel lines in the tank of your Poulan weed eater, you will need to purchase a fuel line kit that includes the correct-sized hoses, as well as a stainless steel cable to assist in the installation. The cable is particularly useful for feeding the new lines into the tank.

Firstly, remove the fuel tank from your weed eater. You will then need to feed the new lines into the tank through the top holes. This can be tricky, so it is recommended to cut the ends of the lines at a 45-degree angle to make it easier to push them through. Once they are in, use needle-nose pliers to pull the lines further into the tank.

The fuel lines should be a tight fit in the tank to ensure a good seal. If the lines are too small, you may need to use some fuel-resistant sealant on the outside of the lines to ensure a tight seal.

Finally, attach the fuel filter and any other necessary components to the lines, and then bolt the tank back onto the weed eater.

The carburetor

When replacing the fuel lines, you'll need to disconnect the old line from the carburetor. Using a pair of needle-nose pliers, carefully pull the fuel line off the metal nozzle. Make sure you have a stable grip on the hose to avoid any damage to the carburetor. Once the old line is removed, you can prepare the new fuel line to the appropriate length and then push it onto the metal nozzle, ensuring a secure connection.

It's important to note that the carburetor has different sides, one with a hole and one without. The fuel line should connect to the side without the hole. Additionally, the carburetor has a metering chamber, which is usually identified by a cover with writing on it and a vent hole. This is where the larger diameter fuel line connects.

By following these steps and understanding the carburetor's function and connections, you can ensure that the fuel delivery system in your Poulan Weed Eater operates smoothly.
